Figs. portions at each end extending beyond the plane of the side flanges, the end edges of the flanges forming shoulders, and a nut and loop on the respective ends of a hoop for engaging the said shoulders, substantially as described.

2. The herein-described shoe or coupling having a base portion, upwardly-extending flanges forming between them an open recess, the base portion extending horizontally beyond the plane of the flanges, and a strapbolt resting at one end in said recess and upon the horizontal projection and at its other end provided with an eye embracing the shoe or coupling, said eye at its lower end being narrower than the horizontal projection directly below it, substantially as described.

3. The combination with the U -shaped channel-iron forming a coupling or shoe, its longitudinal side flanges at one end being provided With notches, of a hoop having on one end a nut to engage one end of said. flanges and a hoop having an elongated eye of Width sufficient to embrace the shoe from end to end and to allow of the passage through it of the nut also, said eye engaging with its outer cross-piece the notches formed in the end edges of the flanges, said shoe hav ing horizontal extensions projecting beyond the end edges of the flanges, substantially as described.

4:. The herein-described shoe or coupling struck up out of sheet metal and comprising a suitable base and parallel longitudinal side flanges, said flanges at one end being notched and forming between them a U-shaped chan nel and a hoop threaded at one end to receive a nut, said threaded end of the hoop fitting in the U shaped channel and the nut bearing on the end edges of the flanges and the other end of said hoop being provided with a loop embracing the flanges and fitting in the notches, substantially as described.

In testimony whereof We affix our signatures in presence of two Witnesses.
